Superior/inferior in what?
If we compare output the British industry appear overwhelmingly superior - by 1941 the British (excl. Empire) produced more of every significant category (planes, guns, tanks etc.) than the entire Axis combined!
I do not negate the ingenuity of German industry, but the German economy simply wasn't capable of going to total war economy until it was too late (1942-) and then had to resort to slave labour and extreme exploitation (and declining quality). The British economy went to total war economy from 1938/39 and stayed there for the duration of the war - without slave labour, extreme exploitation etc. You can say that they paid with their Empire, but after all that was cheap compared to the Germans who paid with their independence, dignity and national identity and pride.
But the post-war years made a significant difference. In Britain it was "relaxation time" upon the hard war years, and clapped out means of production were not renewed. In Germany there wasn't any means of production left (bombed or dismantled by the allies), and it was obvious to everybody that hard work was ahead. The reconstruction of Germany after WWII is one of the most impressive acts in history - in a few decades their economy was in a position better (both in relative and absolute terms) than before WWII! After WWI the Germans turned their frustration into political uproar - that didn't work. After WWII it was turned into silent and hard work - that worked.
